Tetra 44

Tetra 44

Our classic frame with a modern twist; 25 years of perfection optimized for today’s standards.

Our Tetra frame is now offered with a new 44mm head tube and an oversized down tube. These changes create compatibility with tapered steerer forks, increases frame stiffness for a livelier feel, and provides more efficient power transmission.

The Tetra tube set and single, road frame was originally designed in 1987 and has been thoughtfully refined to its current incarnation over the last 25 years. Enjoy this article in Cycle Sport which describes in great detail our formative years and early achievements at the highest level of the sport. As the oldest continuously produced model of carbon fiber bicycle frame in the world, it has evolved to a state of perfection and value unmatched by any other frame.

Tetra Benefits:

Best combination of stiffness and comfort for everyday riding

Tubing is crash tolerant

Lighter than Luna

Highest performance coupled travel frame on market

More About the Tetra

Even bicycle enthusiasts and industry insiders are surprised to learn that Tetra was invented back in 1987 and only four years later was being ridden by Greg LeMond and his Team Z teammates in the world’s most important cycling event, the Tour de France. Greg wore the leader’s Yellow Jersey aboard our Tetra, then less than five years old. Today, nearly 20 years later, Tetra tubing and bicycle frames have been continually optimized; sharpened by improvements in raw materials, manufacturing processes and advantageous frame options.

With the Tetra frames, we saturate carbon fabric with epoxy, then laminate it at 210 p.s.i. and fuse it to pre-mitered carbon tubes using metal dies. Molded in one layup, the resulting joints have long tapered transitions from one tube to the next, following the stresses evenly. This manufacturing process seamlessly marries our roll-wrapped carbon tubing resulting in a frame without molded lugs. Fatigue life for these fiber reinforced joints is appreciably longer than that of adhesive bonds and, coupled with the tubing itself, is grounds for the Tetra’s 25 year warranty.
